Can Cream Hardener Be Used for Fiberglass Resin?

    Identification

    • Fiberglass resin is a liquid form of fiberglass that can be applied to fiberglass bodies for repairs. Used along with the resin is cream hardener, a chemical that activates the solidification of the fiberglass resin for a resulting hard finish.

    Function

    • Mixing 2 percent cream hardener to a selected amount of fiberglass resin allows the mixture to be applied without dripping. This is especially helpful if applied while the substrate is in a vertical position, like a car door or side panel.

    Significance

    • The use of the resin and hardener mixture allows the resulting fiberglass body to be sanded, emulating the ease of working with steel. The result is a smooth, repaired fiberglass body that can take a quality paint job without any apparent dents or breaks.
